When header_size is zero, the expression\n*(buf + header_size - 1) reads one byte before the buffer start.\n\nSince initial_header_size is set to 71 in mpf_ops, the fpga-mgr core\nguarantees the buffer is large enough to reach MPF_HEADER_SIZE_OFFSET.\nThe only real gap is the zero header_size case, which cannot be\nresolved by providing a larger buffer, so return -EINVAL.","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/0d3766fecd9b2db39a18b48021c15c522997ec25","https://git.kernel.org/stable/c/3da8eaf5469eda2353b72038d644fabddb848ce1","https://git.kernel.org/stable/c/43a1974da6bc7ce8f4d1dc1d03d56997428c29c3","https://git.kernel.org/stable/c/a1baee24df72ec8fd1d6925c1d5162ffff4ee3bf","https://git.kernel.org/stable/c/c9ef79e34bc1eac4fd59051e5c7b96a74e59d46f"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:48:17.459049833+00:00"},"epss":{"cve":"CVE-2026-72156","score":0.00215,"percentile":0.11871,"date":"2026-10-31"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
